How to Apply for React Frontend Developer
at 3E
🏢 About 3E
3E is a mission-driven company that helps businesses improve safety and sustainability through EHS solutions. Working here means contributing to products that have a real environmental impact, with a remote-first culture across the EU.
About This Role
As a React Frontend Developer, you'll build data-heavy interfaces like dashboards and charts that enable clients to visualize and improve their environmental performance. Your work on the shared design system will ensure consistency and scalability across products.
💡 A Day in the Life
Your day starts with a stand-up with your cross-functional team, then you dive into coding on a new dashboard feature or refining reusable components. You might pair with a backend dev on API integration or review a colleague's PR, and end the day with a quick retrospective.
🚀 Application Tools
🎯 Who 3E Is Looking For
- You have 4+ years of React experience and are comfortable with TypeScript, performance optimization, and debugging complex UI issues.
- You enjoy building data visualization components (charts, tables) and have an eye for UX in data-heavy applications.
- You can contribute to architectural decisions and code reviews, and you value maintainable, reusable code in a design system.
- You hold a CS degree or equivalent and thrive in cross-functional teams.
📝 Tips for Applying to 3E
Highlight any experience with data visualization libraries (e.g., D3, Chart.js) and performance tuning (e.g., React.memo, virtualization).
Mention your experience with design systems or component libraries, and be specific about your contributions.
In your resume, quantify impact (e.g., 'Reduced page load time by 30%' or 'Built a reusable table component used across 5 products').
Tailor your cover letter to show passion for sustainability and EHS; mention 3E's mission.
Include a link to your GitHub or portfolio with React/TypeScript projects, especially those involving data-heavy UIs.
✉️ What to Emphasize in Your Cover Letter
['Your experience building complex, data-intensive React applications with TypeScript.', "How you've contributed to design systems or reusable components that improved team efficiency.", 'Your interest in sustainability and how your skills can help 3E achieve its mission.', "Examples of performance optimization and debugging you've done in previous roles."]
Generate Cover Letter →🔍 Research Before Applying
To stand out, make sure you've researched:
- → Read about 3E's EHS solutions and understand their core products (e.g., 3E Exchange, 3E Protect).
- → Look into recent news or case studies about how 3E helps companies reduce environmental impact.
- → Check their engineering blog or tech stack (e.g., do they mention any specific tools like Storybook for design systems?).
- → Understand the remote culture: time zones, communication tools (Slack, Jira), and team rituals.
💬 Prepare for These Interview Topics
Based on this role, you may be asked about:
⚠️ Common Mistakes to Avoid
